What is claimed is:

1. A machine for repairing shoulders of roads comprising a main frame,supporting wheels for the main frame, a super-structure carried by themain frame and projecting laterally thereof, a supporting wheelconnected with the outer end of the super-structure, an auxiliary framepivoted to the forward end of the main frame and lying underneath thesuper-structure, grading means carried by the auxiliary frame, andindividual control means connected with opposite sides of the auxiliaryframe for adjusting the grading means relative to the road bed.

2. A machine for repairing shoulders of roads comprising a main frame,supporting wheels for the main frame, a super-structure carried by themain frame and projecting laterally thereof, a supporting wheelconnected with the outer end of the super-structure, an auxiliary framepivoted to the forward end of the main frame and lying underneath thesuper-structure, grading means carried by the auxiliary frame,individual control means connected with opposite sides of the auxiliaryframe for adjusting the grading means relative to the road bed, andmeans cooperable on the auxiliary frame and the grading means forvarying the angularity of the latter with respect to the direction oftravel of the machine.

3. A machine for repairing shoulders of roads comprising a main frame,supporting wheels for the main frame, a super-structure carried by themain frame and projecting laterally thereof, a supporting wheelconnected with the outer end of the super-structure, an auxiliary framepivoted to the forward end of the main frame and lying undereneath thesuper-structure, grading means carried by the auxiliary frame,individual control means connected with opposite sides of the auxiliaryframe for adjusting the grading means relative to the road bed, each ofsaid individual control means comprising a first shaft extendinglongitudinally of the main frame, a second shaft projecting laterallytherefrom and operatively connected with one side of the auxiliaryframe, and a hand wheel connected with the first shaft near the forwardend of the main frame.
